Error - The project rate type cannot be deleted because there is at least one project task type that references it

When deleting a rate type from the rates tab, you may receive the following error message: The project rate type cannot be deleted because there is at least one project task type that references it.

Solution

This message may appear when you have deleted a rate type and also deleted that rate type from some task types at the same time. To work around this you will need to:

  • Close the project without saving
  • Reopen the project and remove the rate type from the task types tab
  • SAVE
  • Reopen the project and now delete the rate type
